This patch moves phy enable/disable calls from pullup() method to
udc_start/stop functions. This solves the issue related to limited caller
context for PHY functions, because they cannot be called from non-sleeping
context. This is also a preparation for using soft-disconnect feature of
udc controller in pullup() method.
